Scott Weiland's widow selling engagement ring

Scott Weiland's widow is auctioning off her engagement ring.

The 48-year-old rocker died of an Ecstasy, cocaine and alcohol overdose in December 2015 at the age of 48, and eight months after his passing, his spouse Jamie hopes the diamond ring he proposed with can now make someone else happy.

She wrote on Facebook: "This is the ring Scott gave me when he proposed.

"Eight months into this chapter of my life, I need to part with it. I am so sad to see it go but it's a truly gorgeous piece and I would love for it to make someone as happy at it once made me."

The 18k white gold marquise cut 2.74 carat diamond ring is listed for sale on auction website eBay, with the opening bid set at $8,000.

After his death, the Stone Temple Pilots rocker was branded "paranoid" by his ex-wife Mary Forsberg Weiland, who also accused him of rarely seeing their two children, Noah, 15, and Lucy, 13.

In an open letter, she wrote: "We don't want to downplay Scott's amazing talent, presence or his ability to light up any stage with brilliant electricity. But at some point, someone needs to step up and point out that yes, this will happen again - because as a society we almost encourage it ...

"Many of these artists have children. Children with tears in their eyes, experiencing panic because their cries go unheard ... [He] was a paranoid man who couldn't remember his own lyrics and who was only photographed with his children a handful of times in 15 years of fatherhood."

And Mary went on to insist her children never wanted their dad to be "perfect", but just to put a "little more effort" in.

She added: "Noah and Lucy never sought perfection from their dad. They just kept hoping for a little effort. If you're a parent not giving your best effort, all anyone asks is that you try just a little harder and don't give up. Progress, not perfection, is what your children are praying for.

"Our hope for Scott has died, but there is still hope for others ... Skip the depressing T-shirt with 1967-2015 on it - use the money to take a kid to a ballgame or out for ice cream."
